In coming days, travelers will encounter lane, roadway and intersection closures on downtown arterials 112th Avenue, Main Street and Northeast Eighth Street, as well as Northup Way in the Bel-Red area.

Main Street at 112th Avenue intersection closure: Main Street downtown will be closed in both directions as it approaches 112th Avenue, from 7 a.m. to 4 p.m. Saturday, Aug. 1, as crews grind and pave the intersection. The work is a continuation of a project by Puget Sound Energy to install a 16-inch natural gas pipe under city streets.

112th Avenue Northeast street closure: This busy stretch of downtown roadway, from Northeast Eighth through the intersection at Northeast 10th Street, will be closed from 9 a.m., Saturday, Aug. 1, to 6 a.m., Monday, Aug. 17. The work is part of a project by the state Department of Transportation to extend Northeast 10th Street east over I-405.

Northup Way lane closures: Workers will close lanes on Northup Way, reducing traffic to one lane in each direction between 120th Avenue Northeast and 124th Avenue Northeast, from Friday, Aug. 7, until mid-September. During that time crews will upgrade the storm water system and pave the street. Also in September, a full closure of 124th Avenue, between Northup Way and Northeast 18th Street, will be needed while crews repave that roadway.

Northeast Eighth Street sidewalk project: Sidewalks, curbs, gutters and other improvements are being made to the north side of Northeast Eighth Street, between 96th Avenue Northeast and Lake Washington Boulevard. Starting Monday, the westbound lane will be closed on weekdays, 8 a.m. to 3 p.m. The sidewalk project will still be in progress in the fall, when all of Eighth will be closed, between 92nd Avenue Northeast and Lake Washington Boulevard, to complete utility work and repave the surface.
